splines

I am erstwhile boat designer/builder with an interest in math and physics. I've long been interested in the math behind CAD curves and surfaces and have wondered why spline curves in most CAD programs don't match the curves a piece of wood or metal takes through control points on a mold or jig...

I am in the process of moving and I am trying to get a good home for 15 K&E spline weights (in orginal boxes, except one, it is in 1/2 the orginal box). They are lead and weigh about 4.5 lbs each. I am sorry if this to the wrong place to put this, but who else would be interested? What would...

Are there any old-style battens & ducks available anywhere. Interested in acquiring the same for lofting lines etc. Aware of MacSurf-type software which I have used but am more interested in using pre-software methods. Would appreciate any feedback advice. Thanks in anticipation
